People stop army column. Soldiers open fire (probably in the air, but not quite sure)

Fire in the Police building starting. Voice behind the camera accuses of pro-government soldiers of starting the fire while pro-Russians are inside (1:50+). Though it can't be seen how the fire was started

Injured city deputy. Killed civilian

Another civilian shot

EDIT: I’ve seen multiple reports of pro-Russian militia leaving Slavyansk for Mariupol, including Chechens with experience in guerrilla warfare. In coming hours (evening – night of the 9th of May) there might occur some real heavy fighting

EDIT2: Apparently government soldiers have pulled out from Mariupol and block all traffic in and out of the city
